  • FIG. 4 is a schematic cross-sectional view illustrating the wireless charging device according to the first embodiment of the present invention.
  • the wireless charging device 3 comprises a circuit board 30, a heat-absorbing plate 31, an inductive transmitter coil 32, and a casing 33.
  • the inductive transmitter coil 32 is contacted with the heat-absorbing plate 31.
  • the heat-absorbing plate 31 is contacted with the circuit board 30. That is, the inductive transmitter coil 32, the heat-absorbing plate 31 and the circuit board 30 are sequentially stacked on each other.
  • the circuit board 30, the heat-absorbing plate 31 and the inductive transmitter coil 32 are covered by the casing 33. Consequently, the circuit board 30, the heat-absorbing plate 31 and the inductive transmitter coil 32 are disposed within the casing 33 to receive a shielding effect. Moreover, the inductive transmitter coil 32 is electrically connected with the circuit board 30 to receive an electric current from the circuit board 30.
  • the heat-absorbing plate 31 is arranged between the inductive transmitter coil 32 and the circuit board 30 for absorbing the thermal energy that is generated by the inductive transmitter coil 32 and the circuit board 30. It is preferred that the heat-absorbing plate 31 used in the wireless charging device 3 of the present invention is a high entropy structure and/or made of a high volumetric heat capacity material, which will be illustrated later. By means of the heat-absorbing plate 31, the equilibrium temperature of the inner components (e.g. the inductive transmitter coil 32 and the circuit board 30) of the wireless charging device 3 is lower than the equilibrium temperature of the inner components of the conventional wireless charging device 1.
  • the heat-absorbing plate 31 comprises at least one opening 310 for increasing the entropy value.
  • the opening 310 is a perforation.
  • the heat-absorbing efficacy of the heat-absorbing plate without any perforation and the heat-absorbing efficacy of the heat-absorbing plate 31 with the perforation 310 may be compared according to experiments.

  • the aluminum heat-absorbing plate with a blind hole or a perforation has an equilibrium temperature 49.75°C, which is obviously lower than the equilibrium temperature of the aluminum heat-absorbing plate without the blind hole or the perforation (53.36°C). Moreover, the temperature difference between the temperature of the aluminum heat-absorbing plate with the blind hole or the perforation and the ambient temperature is lower than the temperature difference between the rude aluminum heat-absorbing plate and the ambient temperature.

  • the heat-absorbing plate 31 is preferably made of a high volumetric heat capacity material.
  • the high volumetric heat capacity material is a material with a heat capacity in the range between 3.40 J/cc-°C and 3.80 J/cc-°C.

  • the casing 33 of the wireless charging device 3 is an encapsulation structure in order to prevent dust or foreign liquid from being introduced into the inner space of the casing 33. Consequently, the possibility of causing damage of the circuit board 30 or the inductive transmitter coil 32 will be minimized. Moreover, since the circuit board 30, the heat-absorbing plate 31 and the inductive transmitter coil 32 are tightly sealed by the encapsulation structure, the encapsulation structure has good waterproof and dustproof characteristics. It is preferred that the encapsulation structure is made of thermosetting resin. Similar to the casing of the conventional wireless charging device, the encapsulation structure of the wireless charging device 3 fails to reduce temperature by using convection to remove heat.
  • the wireless charging device 3 further comprises the additional heat-absorbing plate 31 to reduce temperature by heat conduction and heat absorption.
  • the heat-absorbing plate 31 comprises a main body 311 and plural protrusion parts 312.

Consequently, during operations of the inductive transmitter coil 32, the circuit board 30 and the electronic components (not shown) on the circuit board 30, the generated heat can be absorbed by the main body 311 of the heat-absorbing plate 31. Moreover, since the portions of the plural protrusion parts 312 which are exposed outside the casing 33 are contacted with the ambient air, the heat can be further exhausted to the surroundings of the casing 33 through the plural protrusion parts 312.

  • a first end 341 of the power cable 34 is connected with the circuit board 30.
  • the power cable 34 is penetrated through the casing 33, and thus a second end (not shown) of the power cable 34 is connected with a power source (not shown) for receiving an electric current from the power source and transferring the electric current to the inductive transmitter coil 32. Consequently, the inductive transmitter coil 32 results in an electromagnetic effect.

  • the heat-absorbing plate 51 is contacted with the circuit board 50.
  • the circuit board 50, the heat-absorbing plate 51 and the inductive transmitter coil 52 are covered by the casing 53.
  • the heat-absorbing plate 51 is completely covered by the casing 53 of the wireless charging device 5 according to the second embodiment. Since the heat-absorbing plate 51 is not exposed outside the casing 53, the waterproof and dustproof efficacy of the casing 53 is enhanced. Moreover, the heat-absorbing plate 51 comprises plural openings 510. The number of the openings 510 may be varied according to the practical requirements. It is noted that only one opening 510 or more openings 510 are helpful to increase the entropy value of the overall heat-absorbing plate 51. Moreover, the positions of the openings 510 and the shapes of the openings 510 (e.g. blind holes or perforations) are not restricted as long as the entropy value of the heat-absorbing plate 51 can be effectively increased.
  • the present invention provides a wireless charging device with a heat-absorbing plate.
  • the heat-absorbing plate can absorb more thermal energy in response to the increase of a specified temperature. That is, the heat-absorbing plate is helpful to absorb the heat that is generated by the circuit board and the inductive transmitter coil. Under this circumstance, even if the heat fails to be removed by air convection, the heat-absorbing plate can provide good temperature-controlling efficacy. Consequently, the overall wireless charging device is not overheated, and the safety of using the wireless charging device is enhanced.
